Twidec/M12 Approach Sensor Inductive Proximity Switch PNP NO DC 6-36V, 4mm Detecting Distance LJ12A3-4-Z/BY

Good

Like - light weight ~ 45g, flexible wire, repeatable , reasonable price. M48 P9 test Mean: -0.110833 Min: -0.113 Max: -0.108 Range: 0.005 Standard Deviation: 0.001667 I used the Ender 3 24V as power source. I chose the PNP model so the output is 24V. I used a voltage divider ( 4.7K and 1K ) to reduce the voltage. Only two issues - You need a metal build surface , I use PEI on spring steel, You need to make a voltage divider to connect it to the Z_End_Stop on the ENDER 3 control board.

Worked great. Allows enough current for a 12 volt automotive relay to work. Was able to fit in with a handmade bracket to the shift gate of the stock Can-Am X3 to allow for reverse lights to come on automatically when put in the reverse position.

They work as expected. When the bullet feed tube is filled the collator stops.

Note this is a Magnetic Sensor not Optical Sensor, This will not work for my 3D printer because sensor distance thru the glass bed to the metal Hot plate is too far.

Worked for all of a few seconds and then it stopped. Had my plc flickering

I know its a cheep sensor but quality could be better: wires are so tiny, some sensors doesn't work at all

it' s perfect thanks
